Unfortunately, you made it a political discussion the moment you complained about the ad being about firearms. There is no civil place to discuss legality of firearms on the internet, and the introduction of the topic tends to bring out the worst in people on all sides of the discussion.
A little more info, there is no registry for long guns, only restricted firearms (handguns and those firearms arbitrarily determined by the government to be restricted). I am all for stronger gun control in Canada, and this ad is disingenuous, but it absolutely is a ban (amnesty granted to the owners of newly prohibited firearms until October 2025), not the registry that people are complaining about. A ban not necessarily grounded in facts or reality, as there is no consistency in what gets banned and what does not. E.g., AR-15s are restricted, while the more compact but functionally similar Tavor is non-restricted.
As a sport shooter/hunter (NOT right leaning), I just want consistency in the laws I need to follow haha
Why would you ask a question if you already know the "correct answer"?
